…ounce of gold can be drawn into a wire five miles long, or can be rolled and hammered into a sheet of one hundred square feet. Gold is also the most reflective metal for infrared energy, and the most conductive for thermal energy. So you can see why it is so…

…of hopelessness and helplessness. Some of the symptoms of a depressive episode include anhedonia, disturbances in sleep and appetite, psycomoter retardation, loss of energy, feelings of worthlessness, guilt, difficulty thinking, indecision, and recurrent thoughts…

…because a liquid’s particles are farther apart than solids, but closer than gases. When objects vibrate, their energy moves the matter around it and this is what our ears hear as a sound wave. Intensity is the rate at which sound energy enters the ear. Usually…

…of greenhouse gases. These such gases primarily include carbon dioxide, methane, and nitrous oxide. Our dependency on fossil fuels for energy plays a huge role on our planet’s fate. The coasts of all countries could become immersed underwater if the polar…

…this is the wavelength of visible light between 400 and 700 nm. Scanning electron microscopy uses electrons with energies of a few thousand electron volts (eV) energies 1000 times greater than visable light (2-3 eV) For 3600 electron-volt electrons the wavelength…

…this occurs and the pair re-meet, they annihilate each other, and energy is created. Similarly, energy can be converted into pairs of particles. This is known as pair production, and only works because mass and energy are equivalent. Taking this idea further…

…of it is absorbed, warming the earth's surface. Earth’s surface emits some of this energy back out in the form of infrared radiation. As this infrared radiation travels through the atmosphere, most of it is absorbed by atmospheric gases like carbon dioxide, methane…

…. Matisse gave color absolute freedom, letting it guide the way. "I feel through color, and so by color that my canvass will always be organized." Matisse's work explored an explosion of pictorial energy. "Colors must be thought out." According to Picasso…

…. The function of the id is to provide for the immediate discharge of quantities of excitation, including energy or tension, that are released in the person by internal or external stimulation. The earliest form of the id is a reflex system that releases immediately…
